The Local Climate Zone (LCZ) classification scheme, initially designed to distinguish between standard built (urban) and non-built (land cover) types in terms of screen-level air temperature relevant for urban heat island (UHI) studies, has been widely used for land surface temperature (LST) and surface urban heat island (SUHI) studies. However, some concerns remain about the global suitability of the scheme for LST and SUHI studies in different macroclimate regions. By analyzing and comparing a large number of representative LCZ sites and multi-year remotely-sensed LST data, the aim of this work is twofold. Firstly, to study the suitability of the LCZ scheme, with a focus on the built types, for surface temperature studies in four distinct macroclimate regions, namely, the tropical, the arid, the temperate and the cold. Secondly, to understand the influence of the macroclimate region on the LST and SUHI characteristics of the standard LCZ built types. Results show that the urban LCZ standard scheme is applicable, with varying degrees, to all macroclimate regions other than the arid, where a LCZ subclassification might be essential. Also, it has been demonstrated that most LCZ built types exhibit significantly different LST and SUHI characteristics across the remaining macroclimate regions.

最初设计用于根据与城市热岛（UHI）研究相关的屏幕级空气温度来区分标准建筑（城市）和非建筑（土地覆盖）类型的本地气候区（LCZ）分类方案，已得到广泛应用用于陆地表面温度（LST）和城市地表热岛（SUHI）研究。但是，对于该计划在不同的大气候地区进行LST和SUHI研究的全球适用性，仍然存在一些担忧。通过分析和比较大量的代表性LCZ站点和多年的遥感LST数据，这项工作的目的是双重的。首先，要研究LCZ方案在构建类型上的适用性，以研究热带，干旱，温带和寒冷这四个不同的宏观气候区域的地表温度。第二，了解宏观气候区域对标准LCZ建造类型的LST和SUHI特性的影响。结果表明，城市LCZ标准方案在不同程度上适用于除干旱以外的所有宏观气候区域，而干旱地区对LCZ的分类可能是必不可少的。而且，已经证明大多数LCZ建造类型在其余的宏观气候区域表现出明显不同的LST和SUHI特性。
